New HMI for BrauEule III microbrewery

For the new BRUMAS microbrewery, BrauEule III, we developed a brand-new HMI with a new underlying control system. Additionally, some new innovative features have been implemented, which make BrauEule III one of the best microbreweries available in this market segment.

The Challenge

Since 2003, BRUMAS has been convincing with its high-quality automatic microbreweries, called BrauEule®. Beginners as well as experts value the possibility to choose between the “auto” or “custom” brew programme, which make the brewery suitable for every knowledge level.

Brumas decided to innovate BrauEule by giving it a completely new touch controlled display unit. Within this scope, a completely new control system needed to be developed to run on a new hardware. Additionally, Brumas wanted two brand-new features. The first one is the integrated recipe book, to make it easier to brew different types of beer by just following the instructions on the display. And the second one is the control of the fermentation process taking place in the connected refrigerator.

Brumas decided for TARA Systems’ GUI Services and Embedded Wizard as a GUI technology.

The Solution

Designing an intuitive and modern user interface is the job of professionals. For this part we initiated to get Shapefield, one of our UX design partners, on board.

To understand the whole operating principle of BrauEule, we arranged a creative workshop with all involved parties, where we discussed the process flow of beer brewing and all UX related aspects. Furthermore, we even brewed beer by ourselves, to better understand the fundamentals of the beer brewing process.

After the mock-ups and then the visual design from Shapefield had been approved by Brumas, we started the implementation work. To make the process faster, we were developing the control system in parallel with the GUI implementation, which was possible due to our GUI tool Embedded Wizard. Thanks to the possibility of prototyping on Windows, we could ensure an ongoing testing of the complete software at every development stage, even when the hardware related part wasn’t ready yet. In order to rule out the possibility of misinterpretations, we stayed in continuous contact and discussions with Brumas through the entire development time.

Four months later the underlying control software as well as the GUI developments were finalised and the new BrauEule III was ready to be introduced to the market.

The Result

Thanks to the good cooperation and the commitment of all involved parties, a huge upgrade of the product could be achieved. The new BrauEule III now has a new colour touch display with a completely new user interface and control system, which bring the usability and user experience to a new level. It is the only product available in this market segment with the integrated recipe book and intuitive user guidance. Moreover, the fermentation process taking place in the refrigerator can now be controlled as a parallel process, which allows the user to start a new brewing process at the same time.

In November 2016, BrauEule was presented at BrauBeviale - capital goods exhibition for the beverage industry - and it was a big success. BrauEule has been very well received by the fair attendants and some of them even placed an order instantly. In particular, the intuitive handling, guided brewing process, simultaneous control of two processes and integrated recipe book have absolutely enthralled the visitors. This confirms our conviction that the new user interface worked out to be really logical, understandable and intuitive, which makes the product as a whole even more attractive for the end user.

The new BrauEule is expected to be launched on the market in Q1 2017.

The whole design process was managed professionally from the beginning. The focus was set to the right issues. Work was efficient so every milestone was met right on the tight timeline. For me the result is an extremely good user interface, beautiful design and costs within the budget. Seeing the finished product I am sure I did the right thing choosing TARA Systems as a partner.

It was important for me that the partner responsible for programming understands the practical issues of beer brewing. This criteria was met by TARA Systems. Several brews were performed as part of the program development and helped making the right routines in the program code. Cooperation was at a friendly but always professional level. TARA was extremely supportive - despite scarce resources. Special thanks to Alex, Rudi and Ludwig!
